Software for Processing of Sound Level Meter Data
Kříž, Petr ; Schimmel, Jiří (referee) ; Kurc, David (advisor)
This thesis deals with the measurement and evaluation of noise. Thesis summarizes the basic concepts of acoustics and describes methods of measurement and evaluation of noise, focusing on measurement uncertainty. Part of this work is the implementation of software for processing of sound level meter data NTi XL2 in Matlab including practical examples of its use.

Applications for analysis of tennis player motions
Kříž, Petr ; Beneš, Radek (referee) ; Říha, Kamil (advisor)
This thesis deals with segmentation of tennis player´s body parts for analysis its motion. Testing code was written in C++ with use of OpenCV library. Some image processing techniques such as thresholding, background subtraction or finding the largest contours were implemented. There was used a linear triangulation technique for calculating the 3D coordinates of segmented points.

Didactic program for transient analysis
Kříž, Petr ; Murina, Milan (referee) ; Sedláček, Jiří (advisor)
The aim of this work is to create didactic program for transient analysis in the environment of C++ Builder. For the disposal we have pre-defined bank of inertial circuits, that we can change at will and enlarge with the help of implemented editor of circuits. If we want to make an analysis, we will choose random circuit from offered palette and put in our values of components RLC. Subsequently, we specify if we want to know ´image´ of function F(p) of impulse or transient characteristic, finally we push the button ´Execute´. The program will display demanded ´image´ of function F(p) and simultaneously figure out ´original´ of function f(t) with the help of implemented Heavisides figures. This function is acceptable for display in time, which make this program enable. It is easy to find out by the change of time axis, when comes to stabilization of transient analysis and with the help of moving cross exactly establish in which time it has happened and what is the value of transmission, voltage or current in the curciut at the moment. Achievement results shall be print out.

Adaptive frequency filter
Kříž, Petr ; Hájek, Karel (referee) ; Sedláček, Jiří (advisor)
The aim of this work is to design a filter of the type low–pass of order 5th with Butterworth’s approximation in the range of over-tuning 10 – 100 kHz and if it will be possible so! achieve even higher marginal frequencies. To compare two typical representatives of the frequency filters cascading and non-cascading synthesis from the viewpoint the accuracy of an! approximation function, sensitivity to the tolerance values of components, number of the components (mainly OZ) and viability, especially the possibility of electronic over-tuning in selected frequency range. On the basis of these conditions will be chosen one design, which will be realized later. Further it will be necessary to consider the possibilities of electronic over-tuning and to choose for this over-tuning suitable component, to design user management changes of marginal frequency fm by the help of keyboard + LCD and control application on the PC. For this hardware will be programmed appropriate control software. At the end of this work will be constructed appropriate device, which fullfils requirements written above and will be subjected to the laboratory measurements that verify function of this device. The constructional details of the filter are presented in the enclosure at the end of this work. At the CD are available all materials, which were created during the master’s thesis or which are necessarily concerned.

New town hall for the district Brno-North
Kříž, Petr ; Pechman, Tomáš (referee) ; Sochor, Jan (advisor)
The project describes the design of a new town hall in the new proposed urban structure on the site of a dilapidated complex of military barracks in Brno in Cerna Pole. It derives the mass of the town hall from the proposed urban structure in an exposed corner of the area. Its volume solution reflects the openness and transparency of the town hall building, its structural and material solution speaks about social responsibility and the intention to lead by example.

Interactive Suit for Dancers and its Use
Kříž, Petr ; BURIAN, Vladimír (advisor) ; GREMLICOVÁ, Dorota (referee)
Work Interactive costume for the dancer and his use includes historic development and the first practice for the use of interactivity between the dancer and thecostumes. Part of the development of interactive costumeis also developing the technology. In this case, these are the first experiments with colorillumination costumes, the use of projection "theatergraph" inteligent textiles and digital media. Analysis costume CrossX is also thesubject of my work, because of the two-year project Mr.CrossX, which was created in collaboration with students and professors from ČVUT. I summarize here the development of technological principles for making a suit that illuminates a Dance himself, thus creating interaction.
